I just ordered the Burris 3x9 22lr ballistic reticle scope for my Ruger American rimfire.  It’ll be delivered in a couple days.  Anyone have any experience with it?  There wasn’t really anything good online or on YouTube.  Looks like a great value.

Not that model but i just got the Fullfield E1 4.5x14 with the MOA ret. The glass is very good. Well beyond the price I paid. I too put it on my Ruger American rimfire.

That appears to be like the old FullfieldII rimfire (50yd parallax) scope, but under a different model name that was offered in the Burris combo packages they once had many, many years ago.

I have a 3-9x40 FullfieldII (rimfire) scope that was one of the scopes that came in the combo package on my Ruger 10/22. The other 3-9x40 (100yd parallex) scope I installed on my 30-30. Good glass and solid adjustment clicks on both scopes and have held POI for years.  

If these newer Droptine scopes are as good and reliable as the FullfieldII models are, then they're a solid choice for a rifle without the high cost.

Make sure you're getting the 20019 model with the parallax set at 50yds.  I have one of these and I really like it.  The glass is clear and bright and the build quality is top notch.  My only gripe is the reticle lines could be finer.
